Abstract
The utility model relates to a device which is composed of fan blades, a fan casing and a wind guide cone disc, etc. The utility model is mainly used on a vertical axial-flow threshing machine. The utility model is mainly provided with the fan blades, the fan casing, the wind guide cone disc, an impurity guide cone disc, etc. The cleaning device which is used can further sort grains which are threshed by the existing vertical axial-flow threshing machine. The cleanliness is further improved. The utility model has the advantages of low cost, etc.
Description
The present invention is a kind of cleaning plant of installing in vertical axial-flow thresher bottom, is suitable for the vertical axial-flow thresher.
At present; grain cleaning mainly leans against the grass-removing fan on main shaft top in the vertical axial-flow thresher that occurs on the market; the assorted surplus attraction that the attraction wind-force that produces will be sandwiched in the grain upwards sprays from the top grass outlet; this class type mainly contain Chinese patent (patent No.: 89105416.2, application number: the 97123250.4) type of being implemented.Because grass-removing fan is far away apart from the cylinder bottom, after just entering cylinder, contained the assorted attraction that is difficult to be produced by cylinder top grass-removing fan fully like this in the cereal of threshing and attract to clean, particularly when big feed quantity and cane do broken more obvious when serious.
The objective of the invention is to design a kind of cleaning plant, be disposed at the bottom of vertical axial-flow thresher, the emersion object of thresher is carried out secondary clean, further improve the quality of cleaning of thresher.
Cleaning plant adopts following scheme to realize: blower fan not have independently axle but fan blade directly is fixed on the main shaft of thresher, and the shell of blower fan is fixed in below the concave grate bottom; Air inlet is provided with the gas deflector cone dish vertically downward below air inlet, lead assorted awl dish in the setting of thresher outer casing underpart; Fan outlet is arranged on the below of thresher feeding workbench.
The shared axle of blower fan main shaft and thresher in this cleaning plant, the vanes fixed of blower fan are in the main shaft bottom of vertical axial-flow thresher, and below the bottom of concave grate, the top of frame is furnished with the gas deflector cone dish below air inlet.
The invention will be further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is the A-A cutaway views in the accompanying drawing 1.
Among the figure: the solid line at vertical axial-flow thresher middle part partly is the structure diagram of cleaning plant; Among the figure: grass outlet 1; Concave grate 2; Main shaft 3; Cylinder 4; Feeding workbench 5; Fan outlet 6; Air inlet 7; Belt pulley 8; Frame 9; Gas deflector cone dish 10; Blower housing 11; Lead assorted awl dish 12; Fan blade 13; Thresher shell 14; Tusk 15.
Cleaning plant with reference to accompanying drawing, it has blower housing 11 to be fixed on the bottom of concave grate 2, blower housing 11 bottoms have air inlet 7, the side has fan outlet 6, air inlet 7 vertically downward, fan outlet 6 stretches to the outside of frame 9 below feeding workbench 5, fan blade 13 is fixed on the bottom of the main shaft 3 of vertical axial-flow thresher, the below, bottom of concave grate 2, the top of frame 9; Below air inlet 7, is furnished with gas deflector cone dish 10; Gas deflector cone dish 10 can be fixed on the frame 9, also can be fixed on the blower housing 11.Forming annular channel (hereinafter to be referred as " annular channel ") on the circumference between blower housing 11 and the gas deflector cone dish 10 communicates with air inlet 7.On the lower circumference of thresher shell 14, be fixed with and lead assorted awl dish 12.
Accompanying drawing 2 has reflected the sectional structure of blower fan, and gas deflector cone dish 10 and the axial view projected position of leading assorted awl dish 12, is fixed with some tusks 15 in the bottom of leading assorted awl dish 12, and arrow W direction is the blower fan direction of rotation.
Power is by belt pulley 8 inputs, and the W direction is the thresher direction of rotation among Fig. 1.
The contrast accompanying drawing is further described the operation principle of cleaning plant below: after thresher begins out work; the impeller of blower 13 that is fixed on the main shaft 3 begins rotation; under action of centrifugal force; air-flow directive fan outlet 6; produce negative pressure at air inlet 7 places and force formation air flow direction air inlet 7 in the annular channel; be subjected to attracting the air-flow effect when under the seed that thresher is deviate from, dropping near the annular channel like this, can be under the effect of fan blade 13 outside the discharge machine with wherein foreign material inspiration air inlet 7 backs.The effect of leading assorted awl dish 12 mainly is that foreign material are guided near " annular channel ", improves and cleans effect.
Advantage:
1, blower fan does not have independently axle and drive disk assembly, so that whole dressing mechanism is simple, cost is low.
2, it is less that air inlet is attracted to the seed of blower fan downwards, so that cleaning loss is littler.
Code name in the accompanying drawing 1: cane (x →), clever chaff (→), grain (o →)
